Because you are telling it: HISTCONTROL=ignoredup (strangely, my doco spells it "ignoredups", in plural) means to ignore duplicates (usually this is what you want). Try entering different command lines (e.g. "echo bim" then "echo bam") to test. If you don't want to have duplicates ignored, for whatever reason, just unset HISTCONTROL. I have mine set to "ignore both" -- it then ignores command with leading spaces too. Thus I can easily decide that I don't want to have some command in the history: I tend to do that for somewhat dangerous commands I don't want repeated "by accident". regards - -- t -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAlbNn7YACgkQBcgs9XrR2kZdzQCfQVF079RCNjLK+Ivj4Du9H7TY 7U0AniAgSrDgdoTvVu8GFhXE0BwzFM+7 =2nl6 -----END PGP SIGNATURE-----
